GUERNSEY COUNTY. 533 
This is the Cambridge seam. The quality is seen from the following 
analyses by Prof. Wormley of samples from near the bottom, middle, and 
near the top:

This is an excellent coal. The average percentage of ash is 4.30. The 
average of the fixed carbon is 59.73, which is quite large. The sulphur 
is less than in the larger part of the coals of the State, the average being 
1.13. Of this there remains in the coke 0.633. The coke is compact. 
The coal belongs to the caking variety, and requires a good draft for its 
best combustion. The coal is evidently a strong coal, of high heating 
power, and when burned under favorable conditions must do excellent 
service. It is the best representative of the Pittsburgh type of coal I 
have seen in the State. A section was made at the bank of Joseph 
Stoner, as follows:

This coal resembles that at the Nicholson bank. In both banks the 
vertical joints, or polished planes, are numerous. This, however, is a 
characteristic of the Cambridge seam generally. 
CENTER TOWNSHIP. 
This neni lies directly east of Cambridge. There are several 
mines opened in the Cambridge seam of coal in this township and in the 
eastern part of Cambridge. There was time to examine only a part of 
these. The coal is generally quite uniform in thickness and quality. 
The following section was taken on the land of Mr. E. M. Scott:
